Description: 生成多项式的最高位必须是1。例如：CRC-CCITT标准的16位生成多项式：g（x）= x16+x12+x1+1；阶数r = 16
即：0x11021.最高位通常为1。

即：0x11021.最高位通常为1。-Generating polynomial must be the highest one. For example: CRC-CCITT standard 16-bit generation polynomial: g (x) = x16+ X12+ X1+ 1 order of r = 16 that is: 0x11021. Highest one usually.

Description: CalcCRC8
The CalcCRC8 is used to append an eight-bit CRC to the message. A
successful CRC check results in returning a 0.
Implementation: This CRC will be using the CRC-16/CITT protocol.
A 16-bit wide non-reflected code that starts initially with 0xFFFF.
The final value is XORed with 0x0000. The constant (Poly or G or
divisor) is 0x11021. Note: Crc equals the remainder after 0x11021 has
been subtracted from rData.
Algorithm XOR s bit 7 (the MSB) of the current CRC with the current MSB
of the data byte. The current CRC and byte are then left shifted by
one. This value is then XOR ed with bits 7,4,3,1,0 of the current CRC.
This is done until all bits have been processed.- CalcCRC8
